With the development of the internet, the importance of websites has become increasingly recognized by people. Consequently, the issue of website security has also become more and more attention-grabbing.To ensure the security of the website and prevent malicious attacks and intrusions, developers need to add some security protection code.The following introduces some commonly used website security protection codes to help developers improve the security of their websites.
【en】1. Password Complexity Restriction Code
The security of the password is crucial, and requiring users to meet certain complexity conditions when registering is a necessary security measure. The code implementation is as follows:
(1) Limit the length of the password, generally recommended to be at least 6 characters;
(2) Require the password to contain numbers, uppercase and lowercase letters, and special symbols;
(3) Check the password strength, it is best to use regular expressions.
2. Verify code code
Captcha is a commonly used measure to prevent malicious attacks, which can prevent automated registration, login, and other operations, and protect user information security. The implementation code for captcha is as follows:
(1) Generate images using the PHP GD library;
(2) Use PHP $_SESSION to store the captcha on the server, ensuring the correctness of the verification.
3. SQL Injection Protection Code
SQL injection is a common attack method, which involves inputting some special characters into the page to maliciously inject, modify, or delete content in the database.To prevent SQL injection attacks, you can write SQL injection protection code.
(1) Check if the user input contains special characters such as quotes, semicolons, backslashes, etc.
【en】(2) Perform secure processing of user input to prevent the execution of database commands.
【en】4. Cross-site Scripting Attack Code
Cross-site scripting (XSS) refers to an attack where an attacker can inject malicious scripts into the victim's browser, steal user information, modify user data, and so on. To prevent cross-site scripting attacks, the following code can be used:
Check whether the user input contains script keywords such as SCRIPT.
（2）Escape the user input content to HTML special characters to prevent the execution of malicious code.
